New question #227983 on Graphite: https://answers.launchpad.net/graphite/+question/227983
Using whisper-resize.py on my wsp files is dropping a lot of information For example, here's my file before resizing: https://gist.github.com/tysontate/5500037 (whisper-fetch.py output) http://i.imgur.com/69ImgKe.png (screenshot) $ whisper-info.py used_memory.wsp maxRetention: 315360000 xFilesFactor: 0.5 aggregationMethod: average fileSize: 115372 Archive 0 retention: 21600 secondsPerPoint: 10 points: 2160 size: 25920 offset: 76 Archive 1 retention: 86400 secondsPerPoint: 60 points: 1440 size: 17280 offset: 25996 Archive 2 retention: 604800 secondsPerPoint: 3600 points: 168 size: 2016 offset: 43276 Archive 3 retention: 31536000 secondsPerPoint: 14400 points: 2190 size: 26280 offset: 45292 Archive 4 retention: 315360000 secondsPerPoint: 86400 points: 3650 size: 43800 offset: 71572 After resizing the file with: "whisper-resize.py --nobackup used_memory.wsp 1m:2d 15m:2w 1h:8w 3h:12w 12h:2y", my file now looks like this: https://gist.github.com/tysontate/5500053 (whisper-fetch.py output) http://i.imgur.com/SZcETV5.png (screenshot) $ whisper-info.py used_memory.wsp maxRetention: 63072000 xFilesFactor: 0.5 aggregationMethod: average fileSize: 92476 Archive 0 retention: 172800 secondsPerPoint: 60 points: 2880 size: 34560 offset: 76 Archive 1 retention: 1209600 secondsPerPoint: 900 points: 1344 size: 16128 offset: 34636 Archive 2 retention: 4838400 secondsPerPoint: 3600 points: 1344 size: 16128 offset: 50764 Archive 3 retention: 7257600 secondsPerPoint: 10800 points: 672 size: 8064 offset: 66892 Archive 4 retention: 63072000 secondsPerPoint: 43200 points: 1460 size: 17520 offset: 74956 Is there something I'm missing? I'd like to, if at all possible, resize the database without losing information. I saw that the latest HEAD version of whisper-resize.py includes a "--aggregate" option, but that option doesn't help (in fact, it makes the data loss worse). -- You received this question notification because you are a member of graphite-dev, which is an answer contact for Graphite. _______________________________________________ Mailing list: https://launchpad.net/~graphite-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~graphite-dev More help : https://help.launchpad.net/ListHelp
